john miller, you just heard the police commissioner. what do you draw from that, from what he said this morning? >> well, i think he's framed a couple of really interesting questions. when you have the two suspects, their photographs are out there, they've been out for a couple of hours, they're driving around in a car, and you have to ask yourself, where are they going and what are they doing? based on what do they have with them? they have another pressure cooker bomb. they're carrying that. they have a number of these homemade improvised hand grenades, and they have fully loaded weapons. that is suggesting to a number of the investigators who are looking at what they brought with them that they were trying to find a destination, perhaps another crowd, because now that they've been identified, their schedule has been accelerated, and there is a theory by the investigators on the task force, that they may have been looking for a spontaneous target, something that they could plies their bomb at, attack once again, and to confront police
